Forests and other green plants uses carbon dioxide in photosynthesis thus lowering its amount in the atmosphere. In assumption, we can claim that in the ice ages, the low level temperatures may have caused the carbon dioxide levels to neutralize over these phenomenons, also to note that there were less oxygen-breathing organisms and higher carbon-dioxide dependent performing photosynthesis.
A hypothesis for this observation might be that malaria is not endemic to southern Africa. It is a plausible explanation of a given scientific question.
<h3>Hypothesis and scientific method</h3>
A hypothesis is a plausible explanation of an observation of the natural world, which must be tested by using the scientific method.
Testing a hypothesis involves performing additional observational and/or experimental procedures in order to confirm or reject this assumption.
In this case, the sickle cell allele is found in high frequency in regions where malaria is endemic.

The correct answer would be wind, coriolis effect and land. Hope this helps! :)
Answer: d. All of the above are correct.
Explanation: Natural resources are resources provided by nature. They occur in nature without manmade interference. Natural resources include mineral deposits, land water bodies and the atmosphere. These resources are utilized by man for economic, social and educational purposes. Natural resources can be renewable or nonrenewable resources such as water are renewed by rainfall. Heavy manmade activities such as industrialization, war or natural disasters can deplete these resources.
The wall of the left ventricle is thicker than that of the right - True
The left ventricle pumps more blood than the right - False
<u>Explanation:</u>
Heart has 4 number of chambers. One among these chambers is the left ventricle. Among the four cambers of the heart, the thick one is the left ventricle. It appears below the left atrium. The left ventricle is present in the bottom left part of the heart. When the contraction of heart occurs the blood from the valve called mitral enters the left atrium from the left atrium.
The left ventricle transports the oxygenated blood to the human body. The left ventricle needs along these things for pumping the blood. The right ventricle can function by itself and is more powerful than left ventricle. The right ventricle is responsible in pumping blood to the lungs on its own.
